<A NAME="sec4"><H3>Description</H3></A>
<P>The <B><I>pointer_to_binary_function</I></B> class encapsulates a pointer to a two-argument function. The class uses <SAMP>operator()</SAMP> so that the resulting object serves as a binary function object for that function. </P>
<P>The <SAMP><A HREF="ptr-fun.html">ptr_fun()</A></SAMP> function is overloaded to create instances of a <B><I>pointer_to_binary_function</I></B> when included with the appropriate pointer to a function. </P>
